IMPROVEMENT IN SASH-BALANCE.

Specification lforming part of Letters Patent No. 44,866, dated November1, 1864.

To all whom it may concern Be it known that I, ANDREW B. I-IEsTER, ofKent, in the county of Jefferson and State of Indian a, have invented anew and improved method ot' suspending sash in windows, so as to openand close the windows at pleasure, to be knownI by the title ot` TheSash-Balance g and I do hereby declare that the followingwis a full andexact description thereof, reference being had to the accompanyingdrawings, and to the letters ot' reference marked thereon.

The method is to balance one sash with the other by means otl a oord andpulleys, so that when one is raised the other descends, and vice versa;also, to shorten or lengthen the the cord at pleasure by means of anoriginal apparatus,hereinat'ter described, thereby moving either sashindependentlyv ot' the other.

Figure l represents the window with the cord, pulleys, and apparatusapplied. The cord is drawn around under the pulley B in the toprailofthe upper sash. Each end ofthe oord is then drawn over one ot thetwo pulleys at U in the head ot' the window. Both ends are then fastenedin the apparatus A to the meeting-rail ot' the lower sash.

Fig. 2 represents the apparatus A with its parts exposed. llts principalparts are the roller d, about threefourths of an inch each way, and theforked lever e g h, about halt' an l inch longer than the thickness ot'the sash and in width equal to the length of the rolleraboutthree-fourths ot' an inch. These are arranged in a ease otl wood ormetal or any suitable material. rlhe roller is made fast by its axisabout a fourth or half of an ineh above the sash. The lever is made fastjust under and behind the roller at e, leaving the other end,g h,free tomove up and down. The lever is made forked by being separated into upperand lower parts, g h, at the point f, just forward ot' the roller. Oneend ot' the cord passes through the case just back of the roller at IL,then under the roller between it and the lever, then through aperforation in the upper part of the lever at f, and then hangs looselyover the lower part ot' the lever at g. The other end of the oord passesthrough the ease at t' in front ot' the roller, and istastened to theupper part of the lever.

When the weight of the sash comes on the cord the lever is drawn upwardby means ot" the end of t-he cord at t', and the other end of theeord,bein g clasped between the lever and roller, is held fast. By agentle pressure on the lever at 'h the cord between the roller and leveris loosened, and may be shortened and len gthened at pleasure.

By drawing the loose end ot' the cord downward over the lower part ofthe lever at g the clasp is at once opened, the cord drawn out, aud thesash raised. For heavy sash I put a small pulley or roller in the endot' the lower part of the lever at g to prevent friction.

What I claim as my invention, and desire to secure by Letters Patent,is-

rEhe cap or shield A, inolosing a ro`ler, d, and a forked lever, e g h,in combination with the pulleys B IG and cord thereunto attached, in themanner and for the purpose described in the speeiiieations.
